14 CFR 11.81 (b)

- Specific section from which reliefis sought: For F900EX-EASy N590CL, we request relieffrom the following portion of 14 CFR: §135.156, Arndt 135-120, Flight data recorders: filtered data (d) Compliance. Compliance is required as follows: (4) After April21, 2014, no aircraft flight data recording system may filter any parameter listed in paragraph (c) ofthis section that does not meet the requirements ofAppendix D or F of this part, unless the certificate holder possesses test and analysis procedures and the test results that have been approved by the FAA. All records oftests, analysis and procedures used to comply with this section must be maintained as part ofthe correlation documentation required by § 135.152 (f)(1)(iii) or (f)(2)(iii) ofthis part as applicable.
14 CFR 11.81(c)- Extent and reason for seeking relief: For F900EX-EASy N590CL, we are requesting an exemption from compliance with the above listed portion of the flight data recorders. Compliance with the regulations requires retrofit with EASy II upgraded avionics Load. Considering the large amount ofFalcon aircraft being retrofitted with EASy II upgraded avionics, there is a significant waiting time before being accepted in a Service Center for retrofit. The amount ofaircraft retrofitted monthly is limited worldwide, by the large amount ofequipments to supply. Finally, this retrofit requires a significant downtime to adapt to scheduled maintenance checks in a way to maintain reasonable operational use ofour aircraft. After review, we plan to retrofit our aircraft with EASY II upgraded avionics July 24,2014.
14 CFR 11.8l(d)- Public interest 

### I benefit:. Northern Illinois Flight Center is a Part 135 Air Carrier certificated in accordance with 14 CFRPart 135. Northern Illinois Flight Center operated aircraft, to include F900EX-EASy N590CL, are offered for charter services to the public. Northern Illinois Flight Center charter clientele are primarily business leaders that find it necessary to charter an aircraft in order to maximize their time and availability to operate their business. Chartered aircraft allow business executives and key personnel the flexibility to quickly react and meet obligations to advance their business, thereby strengthening the company's position and help to provide a stablejob market, which in tum strengthens the US economy. Considering that a temporary exemption to allow operations with filtered parameters has no direct impact on the safety ofthat individual aircraft, denial of service to these business leaders to quickly react, grow their companies and provide much neededjobs, would be an undue burden onthe public as a whole. 14 CFR 11.81(e)- Information supporting this petition: This petition for exemption is related to the Flight Data recorder: data filtering to be removed, as mandated by 14 CFR §§135.156 Amendment 135-120. This exemption, ifgranted, would allow us to benefit from the commercial use ofF900EX-EASy N590CL between April, 21, 2014 and July 24,2014. Ifthis petition is denied, then commercial flight operations ofF900EX-EASy N590CL will have to be interrupted until EASy II upgraded avionics retrofit is applied.Granting this exemption would not affect nor degrade the inherent safety ofthe airplane. This exemption deals only with the recording ofpitch control surface position (parameter 15), lateral control surface position (parameter 16), yaw control surface position (parameter 17) and cockpit flight control input forces (parameter 88); it therefore has no impact on operational safety. 14 CPR 11.81(±)- Federal Register summary: Petitioner: Northern Illinois Flight Center Affected Regulations: 14 CPR §135.156(d)(4), Arndt 135-120. Summary ofReliefSought: Northern Illinois Flight Center, seek exemption from section 14 CPR part 135.156 to allow F900EX-EASy N590CL to operate with filtered data from April, 21, 2014 to July 24, 2014. 14 CPR 11.8l(g)- Additional information: Granting this petition would have no effect on the regulatory burden ofsmall businesses, small organizations, small governmentaljurisdictions. Granting ofthis petition would have no effect on the recordkeeping and reporting burdens for any involved parties.

ExemptionNo. 10971 UNITED STATES OF AMERJCA DEPARTMENT OF TRANSPORTATION FEDERAL AVIATION ADMINISTRATION WASHINGTON, DC 20591

In the matter ofthe petition of 

### OPERATERS OF CERTAIN DASSAULT FALCON 900DX, 900LX, 900EXEASy, 2000EX, 2000EX EASy and 2000LX AIRPLANES for an exemption from§ l35.156(d)(4) ofTitle 14, Code ofFederal Regulations 

### Regulatory DocketNo.**FAA-~013-1047**



### GRANT OF EXEMPTION By letter dated November 22,2013, Greg Paxson, Director ofMaintenance, TWC Aviation, Inc.(TWC), 16700C Roscoe Blvd., VanNuys, CA, 91406, petitioned the Federal Aviation Administration (FAA) for exemption from§ 135.156(d)(4) ofTitle 14, Code ofFederal Regulations (14 CFR). This exemption, 

### ifgranted, would allow one Dassault Falcon2000EX EASy and three Dassault Falcon 2000LX airplanes to continue to operate without complying with the prohibition onthe filtering fight recorder data of§135.156(d)(4). Between December 11,2013 and January 31, 2014; the FAAreceived nine more petitions for exemptionfor 14 similar Falcon aircraft operating under 14 CFRPart 135. 

### The petitioners request relieffrom the following regulation: Section135.156(d)(4) requires in pertinentpart that, after April21, 2014, no aircraft flight datarecording system may filter any specified parameter unless the certificate holder

AFS-14-073-E

### 2 possesses test and analysis procedures and test results that have been approved bythe FAA, and maintains that data as part ofits required correlation documentation. The petitioners support their request with the following information: The initialpetitioner, TWC Aviation, stated that compliance withthe regulation requires an avionics system upgrade to the EASy IT avionics load. Because ofthe "large amount of aircraft being retrofitted" the petitioner noted that there is a significant waiting time to be accepted into a facility that can complete the upgrade, and that supply ofthe equipmentis equally limited. TWC also noted that there is significant down time associated with the installation ofthe equipment and that operators seekto install the upgrade during scheduled maintenance checks to "maintainreasonable operationaluse" oftheir airplanes. Honeywell, the manufacturer ofthe upgrade equipment, gave TWC retrofit dates between July 2014 and January 2015 as to when it could accommodate the petitioner's four airplanes. Subsequent petitioners included the identical information andjustifications, including differing retrofit availability dates thattheyhave been quoted between April and September 2014. One petitioner gave anunspecified time in2015 for installation, and one requested 18 months from the compliance date to account for schedule slippage by the service centers. At least one petitioner included as part ofits submission a Dassault Falcon Service Advisory notice, stating thatthe petitioner's airplane was filtering data and that Dassault and Honeywell would notbe able to schedule anupgrade at a service center before the regulation takes effect on April21, 2014. The materials sentby the manufacturers to petitioners indicates that four parameters are subjectto filtering by software with a "cut-offfrequency inside the operational bandwidth ofthe sensor." These parameters are number 15, pitchcontrol surface position, number 16, lateral control surface position, number 17, yaw control surface position, and parameter 88, cockpit control input forces, the last 

### in certain 900EX airplanes. The Service Advisory indicatedthat operators should petition the FAAfor an exemption, and provided the boilerplate language used by many ofthe subsequent petitioners. On January 31,2014, WilliamE. Cummins, Acting Chieflnspector, NetJets Aviation, Inc., 4111 Bridgeway Avenue, Columbus, OH 42319 (DocketNo. FAA-2014-0002) resubmitted its request indicating that Dassault had updated 

### its Falcon Service Advisory FSA-31-30-006- R04:..B as ofJanuary 14,2014, but didnotinclude a copy ofthe advisory or describe whatmay have changed from theprevious advisory. Each ofthe petitioners cited significant financial impact on its operation ifitwas tillable to continue to operate the affected airplanes until they could install the upgrade. The petitioners also noted that the offered EASy II avionics upgrade offers otherfunctionalities such as ADSBOut, FANSlA, ATNB1 and LPV.

### 3 As a group, the petitioners noted that a grant ofexemption "would not affect nor degrade the
·inherent. safety ofthe aircraft" andthat since it only affected recorded data, itwould have "no

impact on operational safety." A summary ofthe petition ofTWC Aviation, DocketNo. FAA-2013-1047, was published in the Federal Register on January 21, 2014 (79 FR 3455). Comments on the petition were due February 10,2014. No comments were received. The FAA's analysis is as follows: 

### The FAA amended the regulations prohibiting flight datarecording filtering in 2010, with

### four years for compliance. Materials submitted by the petitioners indicate that they may have been unaware ofthe filtering taking place on their airplanes and the aircraft and avionics manufacturers' inability to schedule compliant equipment upgrades as late as October 2013. While each operator remains responsible for the operation ofits airplanes and the equipment installed on it, the FAA understands that some operators have experienced unforeseen delays in scheduling their airplanes for upgrade for reasons not under their control. The FAA finds that good cause exists to 

### allow additional time to retrofit the subject aircraft with compliant equipment. The FAA does not agree with any assertion that flight recorder systems are not safety equipment simply because they do not affect the operation ofa given flight. Flight recorder dataare often the only evidence ofairplane problems available to investigators following aircraft accidents and incidents, and filtered data were shown to have significantly inhibited the investigation ofthe cause ofa well-known aircraft accident, possibly delaying the corrective action that was necessitated. However, because the subject airplanes will still be recording flight data and the limitations are known, the FAA agrees that a limited time to complete the upgrades is appropriate and that the public interest will be served by allowing continued operation ofa limited number ofairplanes. This grant ofexemption includes a list ofthe identified airplanes that may take advantage of this exemption relief. Reliefis limited to those airplanes identified in the list. Operators of other airplanes ofthe models noted may petition the FAA to be included in the relief, but must have written FAA approval before suchreliefmay be exercised. All ofthe airplanes included on this list are subjectto all ofthe conditions and limitations included in this petition even if they differ from a petitioner's initial request. Operators that fail 

### to comply with all ofthe listed conditions and limitations are prohibited from continued use oftheir airplanes after April21, 2014, until the aircraft are fully compliant with §135.156(d). All modifications to airplanes necessary to comply with the flight recorder filtering regulations of 14 CFR Part 135 mustbe completed as soon as possible, and no later than 16 months from the date ofthis exemption. Once modifications are completed on an airplane, the reliefprovided by this exemption tenninates. No extensions ofthis exemption will be considered.
